Hello, my computer is infected with Sirefef, and I don't know what to do! I noticed it last night when strange music began playing on my desktop, and Microsoft Security Essentials became disabled. I ran Malwarebytes and restarted my computer, then reinstalled MSE. I scanned my computer with MSE which supposedly "found" and "deleted" the threats, but suddenly in the middle of scanning I was given one minute before being forced to restart my computer. Right now I'm running Safe Mode with Networking. My computer is Windows 7 Home Premium 64-bit. I'm not very good with computers, please help!
